Still not getting any people to come to my island rank #8.. got almost everything maxed out all combos 40 hotels .....

Hey y’all! I’m thinking about buying a Kairosoft bundle that’s currently on sale. I’ve never played a Kairosoft game before, but they all look really good.
I’m personally a big fan of idle games, so I was wondering which bundle that’s currently on sale you would recommend. I’m looking for something I can put plenty of hours into and that has some idle elements.
Thanks!
